Meta-Analysis of Dance Versus Other Exercise for Cognitive Impairment

A systematic review and network meta-analysis by Ye Zhao includes 209 randomized controlled trials with 3,773 participants. It compares dance to other exercise modalities for outcomes like global cognition, working memory, and physical performance in individuals with mild cognitive impairment or dementia. The analysis calculates standardized mean differences and p-values using a random-effects model.

Use Cases

• Compare the efficacy of dance versus other exercise modalities on global cognition using MoCA scores from the network meta-analysis.
• Rank intervention effects on working memory and attention outcomes using Surface Under the Cumulative Ranking Curve (SUCRA) values.
• Analyze the comparative impact on physical performance and mood outcomes across different exercise types from the included trials.

Strengths

• Analysis is based on 209 randomized controlled trials, providing a broad evidence base.
• Includes data from 3,773 individual participants across the included studies.
• Employs both pairwise and network meta-analysis methods within a random-effects model.

Limitations

• Several favorable ranking results for dance are driven by single studies, indicating sparse evidence in parts of the network.
• The dataset is a static PDF summary of 273.1 KB, containing aggregated results rather than raw trial-level data.
• Comparative conclusions are limited to the specific outcomes (e.g., cognition, physical performance) measured in the included trials.
